Survival of peas, peaches and prenatal pigs

Article Abstract:

Species evolve a variety of strategies for species survival, but there are some species that evolve similar strategies through convergent evolution. An example of this phenomenon occured in the evolution of the reproductive structures of peas, peaches and pigs. In all three species, there is overproduction and subsequent reduction in number of potential young, depending on available resources. The elimination of less competitive young to ensure greater survival chances for the more competitive young appears to be a form of natural selection at the prenatal stage.

CONTESTING CONSENT: THE CHALLENGE TO COMPULSORY NEONATAL SCREENING FOR PKU

Article Abstract:

Parental consent laws for health screening of newborns can result in conflict of ethics. While parents are often recognized as acting in the best interests of their children, some decisions may interfere with optimum medical care. Screening infants or congenital hypothyroidism is one example, in which parents declined to give their consent to the potential harm of their child.
